Target man: Wenger wants to strengthen the Arsenal midfield in the summer

Liverpool boss Jurgen Klopp, who was Gundogan’s former manager at Dortmund, is lso a firm admirer of the player and has asked to be kept informed about his situation.

Gundogan joined Dortmund from Nuremberg for £4million in 2011 and has established himself as one of Europe’s most sought-after midfielders.

The player stated publicly this week that there was “nothing new to report” on his contract situation as Dortmund close in on Bundesliga leaders Bayern Munich, who are now just five points clear.

Last month Dortmund rejected rumours in the Spanish media that Gundogan had already reached an agreement with City. Dortmund replied on Twitter: “Really? We should know about that, shouldn’t we? Truth is, we don’t know anything about that”.
